Oops, They did it again and again—those Industrial Wind Turbines

Ontario’s industrial wind turbines (IWT) recently reminded me of the Britney Spears hit in the year 2000, “Opps…I Did It Again” and like she repeated in the song; Ontario’s IWT have, “done it again”!  How wind performed on November 9, 2021 is atypical! At the midnight hour those IWT generated quite a bit of unneeded power running at 37% of rated capacity (4,568MW) generating 1,693 MW but eleven hours later they were generating only 65 MW and running at 1.5% of rated capacity (4,307MW) when demand was considerably higher.

If we jump ahead to the following day November 10, 2021, at Hour 5 (5AM to 6AM) those IWT were running at 21.4% of their capacity generating 959 MW but by 11 AM their output had collapsed and they were running at only 1.7 % of capacity producing 72 MW despite the fact demand had increased quite a bit from 5 AM.

As one should surmise, unlike nuclear, hydro or gas generation; IWT (solar also) generation is dependent on the weather. As is obvious, from just the past two days, IWT are extremely intermittent and therefore should be considered unreliable. Thanks to the McGuinty/Wynne led Ontario Liberals IWT were granted special treatment commanding “first to the grid” advantageous rights.

Needless to say, Ontario’s grid operator, IESO, must deal with the vagaries of generation from IWT presumably causing much more intense scrutiny in situations where demand is increasing but variable generation from wind and solar is falling. The same situation applies when demand is falling but variable generation from IWT are quickly rising.  Their job would be much easier without variable generation and ratepayer bills would undoubtedly be quite a bit lower!

It would be a much better scenario without variable wind and solar instead of getting ready for the “Oops” when we in Ontario experience the problems they had to confront  in California, South Australia, the UK (in time for COP 26) and of course the Texas power crisis in February of this year that cost many lives.

Hey, Premier Ford, take away the special rights granted to those IWT and: “don’t, do it again”!

PS: A contact of mine sent me this graph that shows the ups and downs of industrial wind generation outlined above. A picture is worth a thousand words as the expression goes!
